How to Hone a Straight Razor: Whetstone Grits and the Basics

Honing a straight razor means restoring its cutting edge by working the blade through progressively finer whetstones, a job done only occasionally and quite distinct from the near-daily stropping that keeps a sharp edge sharp. When I first picked up a straight razor I assumed honing was something I would do constantly. In practice I have honed mine a handful of times in years, and stropping does almost all the day-to-day work.

Honing versus stropping

Honing and stropping are different jobs: honing removes metal to reshape the edge, while stropping only realigns and polishes the edge you already have. Stropping draws the blade over leather or fabric and straightens the microscopic foil of steel at the very edge, which bends with use; it removes no meaningful metal. Honing uses an abrasive stone to grind away a tiny amount of steel and actually re-form the bevel. The practical rule shavers live by: you strop before nearly every shave, and you hone rarely, often many months apart. Confusing the two is the most common mistake, so it is worth reading how to strop a straight razor alongside this.

When honing is actually needed

A straight razor needs honing only when stropping stops bringing the edge back, which with proper care can be many months or longer apart. There is no calendar for it. The test is the shave: with good lather and a clean stropping, a keen razor cuts smoothly, and when it starts tugging, pulling, or feeling dull despite all that, the edge has worn past what stropping can fix. A razor stropped well before each shave commonly holds for many months, and some go a year or more, depending on the steel and your beard. Reaching for the stones too early just wears the blade down faster than it needs to.

The whetstone grits involved

Honing runs through a progression of whetstone grits, typically from around 1,000 up to 8,000 or higher, finishing very fine. You do not use one stone; you climb a ladder. A coarser stone near 1,000 grit sets or repairs the bevel, a mid stone around 3,000 to 4,000 grit refines it, and a finishing stone of 8,000 grit or more polishes the edge to a shaving keenness, with many shavers going finer still on a 12,000 grit stone or a pasted strop. Each step removes the scratches left by the one before. The numbers shift between stone systems, but the direction never does: always coarser to finer, never skipping back.

The basics of the motion

The core honing motion is the blade laid flat on its spine and edge, drawn across the stone edge-leading at a steady, consistent angle, flipping over the spine between passes. Because the spine rests on the stone, it sets the angle for you, which is what makes a razor different from free-hand knife sharpening. Both spine and edge stay in contact, the strokes are light and even, and you do equal passes on each side so the bevel forms symmetrically. The first time I tried it I pressed far too hard; honing is about consistent contact and patience, not force. Most stones are soaked or splashed with water first to float the swarf away.

Why many shavers send it to a pro

Many people skip learning to hone and send the razor to a professional honer instead, because the skill is real and the blade is expensive to ruin. Getting a true shaving edge takes the right stones, a rock-steady angle, and the judgement to know when each grit is finished, all on a blade that costs a fair amount to replace. A professional turns a tired edge into a shave-ready one reliably, and plenty of committed shavers happily pay for that once or twice a year while they master stropping and shaving first. There is no shame in it; honing and using a straight razor are separate skills. Build your shaving confidence first with how to shave with a straight razor.

Keeping an edge between honings

Good stropping and good drying are what stretch the gap between honings. A razor stropped correctly before each shave, rinsed, and dried fully so the steel never sits wet keeps its edge far longer and resists the rust and pitting that force an early hone. A dull or rough edge also drags on the skin, which is when razor burn and nicks creep in, so a properly maintained edge is kinder to your face as well as your wallet. For the wider routine, see the wet shaving guide.

Anything to do with your skin matters here too: if shaving leaves the skin painful, persistent, or infected, that is a job for a pharmacist or doctor rather than a sharper edge, and authorities like the American Academy of Dermatology and the NHS cover those issues well.
